In many Spanish regions with water scarcity, this fact can be an argument to make wastewater reuse necessary. In this work, a biologically treated wastewater from a cotton thread factory was subjected to nanofiltration (NF) in two ways ...

A combination of coagulation and ultrafiltration (UF) processes for textilewastewater reclamation was investigated using various types of coagulating chemicals such as polyamine, alum, polyaluminum chloride (PACl), an ...

... study the application of the nanofiltration process was investigated mainly in the retention of color and chemical oxygen demand (COD) present in textile industry wastewater. Nanofiltration experiments were carried out in a pilot unit, operating in crossflow. Three different types of spiral woun ...

The present work experimentally studied the clarification of wastewater using the electroflotation technique (EF) with aluminum electrodes. In the first part, we have studied the principal parameters (feed tension U ...

... any significant improvement. Thus, single stage 5 mm MF followed by 100 kDa UF was selected as the best prefiltration train to NF that permits the textile producer to reclaim indigo dyeing wastewater. This paper presents a comparative study of MF/UF as prefiltration to NF in the reclamation of indig ...
